Probably the same stone

96 more stones that look like the same stone offered again, with no laboratory number in common: the same main stone, the same weight to 0.01 carat (one main stone of 1 carat or more), and every quality known in both sales the same (origin, treatment, colour, clarity, shape), with nothing that differs: the same kind of jewel, the same other gems and metal, no other signature, prices within three times. Not proven: to check by eye, photographs side by side. They are kept apart from the stones above and from every price index.
